Ag Oasis began as, and remains, a family business. We started as a platform for the future, with the focus of allowing more people to work together in the same direction – everyone brings something different to the table – to grow and to provide an opportunity to provide high quality, nutritious milk.

Ag Oasis has grown to include two dairies in Kansas and two in Oklahoma and are proud to say our company represents wide open thinking and a positive outlook for the future.

Tuls Dairy

1993

Brothers Todd and Pete Tuls saw an opportunity to move from southern California and began Tuls Dairy with 1,800 milking cows.

Tuls + Hemann Partnership

2000-2002

A new partnership formed between Pete Tuls
and Brian Hemann What started as a platform
for one families' future has now provided a
place for multiple families to work together in
the same direction. Brian came from his own
family run dairy farm, helping grow the herd
from 1,800-2,400 milking cows.

Oklahoma Expansion

2003-2005

Looking for new opportunities to expand, Lost
Trail 1 and 2 were purchased and remodeled
allowing an expansion of the milking herd to a
total of 5,600 milking cows between the 3
locations. With this new growth we recognized
the skills of longtime employee Efrain Estrada
and gave him the opportunity to manage Tuls
Dairy.

Mas Cow Dairy

2006-2007

With the addition of building Mas Cow Dairy
located in Moscow, Kansas the herd expanded
to 8,300 milking cows between the 4 sites. The,
expansion created new positions and keeping
with family tradition, Efrain Estrada’s brother,
Jose Estrada, was given the opportunity to
manage Mas Cow Dairy.

Lost Trail Dairy

2007-2009

With further enhancements to all 4 facilities it
allowed us to grow the herd from 8,300 to 9,750
milking cows.

Pete Sr. Leaves to Sail the World

2010-2011

In 2010, Pete Sr. set sail across the world for a
new adventure. Clint Anderson joined the team
at this same time bringing his experience from
Allied industry along with experience with
large herd management. This qualified him to
fill an Operations Manager Position. At this
point in time, they had experienced 450%
growth within four locations across two states,
totaling 10,800 milking cows by 2011.

Partnership with KDI

2012-2013

Looking for new ways to create opportunity
and new relationships, Ag Oasis and Kansas
Dairy Ingredients began working together. KDI
built an ingredient plant in Hugoton, KS which
Ag Oasis supplies milk to. Ag Oasis reaches
11,150 milking cows.

Kansas Dairy Ingredients Partnership

2013

This year brought a shift in mindset to take a
step back and to be more environmentally
cautious and community driven. Partnering with
Kansas Dairy Ingredients enabled us to bring
together industry knowledge and expertise to
begin manufacturing concentrated milk
products and new ways of marketing. This
allowed Ag Oasis to grow to 11,300 milking
cows.
